Inboards cannot compete with four stroke outboards if you are talking
similar horsepower. They weigh more, and the way they are hooked to the
prop is less efficient, whether you are using one via an outdrive or a
propshaft angled through the boat's bottom. The outboard's drive system is
less complex than that of an outdrive, and more reliable, plus you can
pull it completely out of the water. No big gasket on the transom, either.
The "straight inboard" shaft assembly is less complex than that of the
outboard, but...the inboard prop is angled. That is less efficient.


Depends on the size of the boat.
